CARBURETELQ.

.To all wit/jm it may concern:

Be it known that I, WILLIAM H. Hoornn,a

citizen of the United States, residing at San Francisco, -in the county of San Francisco and State tain new and useful lmyn'ovements in Carbureters, of which the following is a specification.

A My 'invention relates to earburcters in which air is impregnated with a combustible substance, such as gasolene, in order to supply an explosive mixture for operating gaa engines and for any other purposes for which such a combustible mixture is adapted to be used.

Itrelates more articularly to means for insuring a thorough) and complete mixture of air and gasolene, to means for automatically regulating the supply of gasolene in proportion to the required consumption of explosive gas, to means for causing the current of air to operate the gasolene-supply valve, and to special improvements in construction and arrangement, all tendingY to the production of a simple, inexpensive, and efficient carburetingapparatus. l l

embodiment of my invention is fully hereinafter described and is'shown in the acvbottom and companying drawings, in which igure 1 is a side elevation of the carbureter with 'the airinlet -valve casing and a means for coupling to an engine attached. Fig. 2 is an end elevation looking toward the coupling. Fig. 3 is a plan view of the carbureter with its cover, screens, and packing removed. F ig. 4 is a longitudinal section,

The carbureter proper is composed of a chamber 1, having, preferably, a rounded a flat opentop, which is closed by the cover 2, securedA by screws, as shown, or in any suitable manner. The chamber is formedat both ends with projecting ears 3. To the' ears at one end is bolted the valvechamber 4, having the air-inlet 5 and provided With the lift-valve 10. The air-valve chamber communicates, of course, with the interior of the carbureter. The valve 10 is loose on the stem 6, its hub or sleeve 7 being guided by such stem. On the stem and be tween the valve and the wall of the valvechamber is a coil-s ring 8, which tends to keep the valve seate A screw 9 bears upon the end of the stem 6.

The side walls and bottom of the chamber spcincation of Letters Patent. Application filed April 28, 1905. Serial No. 257.887;

of California, have invented ccr- Patented Oct. 2, 1906.

1 are formed with a series of grooves 11, movable screens 12, made of .fine wire-gauze, and the spaces between these screens are packed with any suitable material, as shown at 13, which `will be easily permeated bythe combustible iluid. I have found ordinary excelsioi' to be well adapted for use as such a packing. The series oli-screens extends sub-A stantially from the rear to the front ofthe chamber', and any number can be employed, according to the size paratus.

The cover 2 1s formed with an upward eX- tension 14, which has an upwardly-tapering bore communicating with the interior of chamber l and with an internally-threaded boss 15, to which the gasolenesupply ipe is to be connected. A tapered valve 16 1'i)ts the seat formed by the tapered bore and when lowered admits gasolene in a quantity regulated by tho extent of its movement. To the lowerI end of the valve 16 is loosely connected parallel inchned a lever 17, pivoted at 18, and whose long arm is forked or otherwise formed so as to embrace the valve-stem 6 just above the sleeve of theA valve.

As the gasolene-inlet is directly above the lirst ofthe series of screens in the chamber 1,

in which are set the inclined reand capacity ofthe apsuch gasolene falls upon the screen and, owing to the incline lof the latter, is somewhat obstructed as it Hows downwardly, so that itis compelled to penetrate the screen throughout its extent and .to penetrate the adjacent packing instead of fa tom. As the screen lies directly across the incoming air-current and the gasolene is distributed over its surface and throughout the packing andthe successive packings as the supply continues, the mixture of air and gasolcne is quickly and uniformlymade, with the an explosive or combustible gas or vapor.

At the forward end of the carbureter is bolted a plate 19 or two associated plates, with whic is formed or to which. is secured an internallythreaded hollow coupling 20, adapted to be connected to the air-inlet of the engine. A deep slot or recess is formed within this pla-te, as indicated at 21 in Fig. 4. The plate has an opening which communicates with the exit-opening at the' forward end of chamber 1. -Within the slot in the ling directly to the botl '95 most effective results as to the production of plate` 19' is theaircontrolling gate 22, which v by the action ot the engine as `movement to the gasolene-valv-,

forms a part ot a sleeve 23, mounted on a pin 2li, secured in plate 19. The sleeve has a handle 25, and its motion and that of the gate are limited by the projection 26, which strikes the coupling 2O at one limit of movement, and by an adiustable screw-stop 27, which meets the handle at the limit of the pposite movement. The interior of the coupling 2() instead of being completely round throughout has webs Z8 arr-angel n angular relation, so that the gate can be adjusted with great nicety relatively to the apex of the angle in case a very' small supply' of gas is required. f

In the operation of the carburetor and supposing it to be attached to an. engine the initial turns of the 'engine-shaft will cornnience drawing in air. The suction raises the air-inlet valve, and its motion causes the lever 17 to communicate a proportionate Y unseating the same and admitting gasolen, which niingles with the air and toi-ins the explosive mixture which is carried into the engine. The extent to which and the frequency with which the valve will be unseated, and hence the quantity of gasolene supplied., depends upon the quantity and rate ot' the gas-supply required by the engine, higher speeds producing a proportionate increased supply et gasolene and lower speeds a proportionatelydiminished supply, and vari ations in the supply of gas to the engines are instantly i'esponded to by relative variations 'in the gasol iene-supply, the gasolene-valve beingq entirely automatic in operation and controlled it affects the supply of air.

l use the term gasolene l in this applica- L. tion as illustrative of all liquids which can oe iised in mixture with air for `forming a combustible gas oi' vapor.

described andshown in the l do not limit myself to the specific details of construction and arrangement herein accompanying," drawings, as l. desire to avail. myself ci' all vmodiications and equivalents as fall properly within the spirit of my invention.

l. In a carbureterya chamber having an lair-'inlet and a gasolene-inlet, a series of inclined screens in said chamber placed in line with the air-inlet, and a packing between adjacent screens.
